We are not working on a 6.1.3 jailbreak, that would be too much efforts
for a minimal update. We're waiting for a major release. (Pod2g)

Look, I said "the next jailbreak" I never said 6.1.3. if you read that article you'd see I said 7.0.x or maybe even 7.1.x. Don't read unconfirmed information. iOS 6.1.3 Untethered Jailbreak not yet. Sorry.(P0sixninja)
